Asafa Powell set another world record in the 100 meters, and suspects he can go even faster. The world's fastest man improved his record Sunday, winning a heat at the Rieti Grand Prix in 9.74 seconds despite easing at the end.

Asafa Powell bettered his own world record in the 100 meters Sunday, running 9.74 seconds at the Rieti Grand Prix. The Jamaican set the mark during one of the two heats to reach the 100 final. Powell, who has run 9.77 three times, finished third in the 100 last month at the track-and-field world championships in Osaka, Japan.

World champion sprinter Tyson Gay withdrew from the 100-meter race Friday at the Golden League meet but will compete in the 400 relay. "Gay is still feeling the strain from the world championships, where he ran no fewer than nine races in eight days," Weltklasse meet organizers said on their website.
